Just what the title says. I have 4 pounds of Tac and want to try it with the 123. Any help or previous experience is appreciated. I have lapua brass and cci primers if that helps. Any velocities would be helpful too (I have an 18" barrel)

Sorry guys, completely missed this until today.
I've loaded a lot of TAC under various bullets. My best loads under the 123 AMAX have run about 27-29 grains, depending on the rifle.
Start at 27 and work up slowly. My bet is that your most accurate load will be between 27.8 and 28.8 grains.
Watch your brass carefully, because I had a load that was incredibly accurate in my 19.5 inch rifle that was overpressure in my 28".
